The Organization of Sequences in Chromosomal DNAd us: there were many rings to be found among the denatured chains and unidentifiable material. Bacterial and phage DNA’s did not produce these rings. Since that time we have produced these rings (called “slipped rings”) from every species of eukaryotic DNA that has come into our hands, including .

Gene Masking in Cell Differentiation: The Role of Non-Histone Chromosomal Proteinsy 1960’s in which the efficiencies of DNA and nucleoprotein as templates for the synthesis of RNA by bacterial RNA polymerase were compared. In all these experiments it was found that DNA was a much less efficient template when it was present as nucleoprotein than when it was free. These early exper

Pretranslational Control in Embryonic Differentiationich may be regulated either at the level of transcription or translation or intermediate levels. Because of their high rate of RNA and protein synthesis, embryonic tissues and rapidly regenerating tissues like the hemopoietic cell lines are most suitable for such investigations.

With the exception of mitochondrial RNA polymerase , these enzymes are located in the cell nucleus although recent reports describe the existence of a cytoplasmically located enzyme .

A Protein Factor Influencing Mammalian RNA Polymerase Bt yet been identified. This leads to the operational problem that we do not know how extensively the chromatin may be broken down and still allow a clear functional analysis. Moreover, a large part of the chromatin seems to consist of elements, such as repeated DNA sequences, whose function remains
